" Referring now particularly tov .thedrawfv f 7a ings wherein-likereference charactersindi cate like parts and more lespecially to lllig-Vures 1 to 11 thereof, it will be noted that rthe door comprises a pairof side rail sections 10 f and a top rail section 11`of similar crosssec# Y tional configuration as will be' apparent from Figures Q, 3y and4. Each of these lrail sec#V tions is in the form of a substantially U-,shapedf member in cross vsection provided adjacent the longitudinaledgesthereof withv ay dove-tail groove`v 13. The.- longitudinal edges ofeach'rail section are beveled or inclined` as shown at 12 for a purposeto'appear more fully' hereinafter. Arrangedin each open end of the toprail section 11 is a spacing bar. section or unit 14 of a substantial A`I-'beam cross section. Fach of these members .includes a -pairoflaterally directed flanges 15 each provided 'with a'par-allel outer face16 and-an inner inclined face 17., lilxtendingv from the opposite sideofthe web of each spacing unit 14 is a pair of spaced parallel flangesl.18 the outer faces of kwhich are formed with dove-tail;y ribsf19.. Aseach of the rail sections 10 and 11fis provided with dove-.tail recesses13Saforedescribed it will be" apparent that the units 14 may beassembled with the adjacent ends of the side rail sections 10 by slidingthe units 14 longitudinally of the side rail members 10 with the ribs 19thereof in engagement with the dove-tail grooves 13. Each of the units14 is provided, in the web thereof, with an aperture for accommodating atie rod 2O which is adapted to extend longitudinally within the top railsection'll with the threaded ends thereof extending through the saidapertures inthe webs of the units 14 whereupon clamping nuts 21 may bethreaded onto the ends of these rods. Thus in assembling the structurein a manner to be explained more fully hereinafter the upper railsection together with the spacing bar units 14 and the tie rod and nutsmay be assembled withthe side rail sections as a unit.

When the units 14 together with the tie rod 20 have been assembled withthe top rail section 11 in the manner aforesaid7 with the nuts 21thereof loosely threaded on the ends of the tie rod, then this unit maybe assembled with the side rail sections by slidably engaging thedove-tail ribs 19 of the units 14 with the dove-tail grooves 13 of theside rail sections. 1 The flanges 15 project into the space between thetop or outer edge of the top `rail section and the relatively heavieredge portions of the section 10 which are provided with the dove-tailgrooves 13, with the parallel faces 16 thereof bearing against thevertical walls of the rail section 1l. rllhus weaving strains or otherstresses tending to disalign the door are successfully resisted by theconnection between the side rail sections and the top rail section orany of the other transversely extending sections, particularly 40g whenthe parts are further united by the tie rods in a manner to be morefully referred to hereinafter. i

Each s acing bar unit 14 has its web thereofextenc ed at one end toforni a projection 14 which extends longitudinally beyond the lateralflanges 15 to abut the ends of the flanges 23 of the anel frame unit22assoc1atedw1th thetop rail section and to abut that portion of theadjacentend of the top rail section 11 that is provided with the grooves13. The flanges 15 of the unit 14 engage the vertical side walls of thetop rail ksection 11. v

A panel framing 22 is adapted to be associated with the top rail section11 and the side rail sections 10, this panel frame'unit 22 including apair of spaced parallel flanges 23 provided with dove-tail ribs 24adapted to engage the dove-tail recesses 13formed adjacent the edges ofthe top andside rail sections. `Each of the units 22 further coniprisesa flange 25 constituting a fixed stop or a panel 26, the unit also beingprovided with a shoulder 27 against which a removable panel stop 28engages. As shown in Figures 9 and 10 the removable panel stop 28 isprovided with a plurality of apertures 29 while the unit 22 is providedwith a corresponding number of threaded apertures 30 whereby theremovable panel stop 28 may be secured in place against the shoulder 27by means of screws for holding the panels 26 in place.

One of the panel frame units 22 as mentioned hereinbefore is adapted tobe associated with the top rail section 11 and one of these units witheach of the side rail sections 10 and the abutting ends of these frameunits 22 at the juncture of the top and side rail sections are chamferedor bevelled as indicated at 31. rlhe engagement of these chamfer-edsurfaces also tends to limit and properly position the top rail section11 with reference to the side rail sections in assembling the door. Thuswhen the unit 11 has been moved to a position where its outer edge is inalignment with the upper ends of the side rail sections then thechamfered portions of the panel `framing of the sections will engage.Vln this position of the parts the nuts 21 are in alignment withapertures 32 formed in the outer wall of each of the side rail sections11 whereby a suitable tool such as a screw driver may be inserted totighten the nuts 21 upon the tie rod 20 to thus rigidly unite the units14 with the upper ends of the side rail sections 10 owing to the bindingaction occasioned between the ribs 19 and the grooves 13. Theseapertures are closed by means of plugs 33 threaded therein.

The side rail sections 10 are united at the bottom thereof by means ofan assembled unit indicated generally in Figure 7 by the referencecharacter 34. This unit consists of a pair of kick-plates 35 eachprovided with a plurality of spaced lugs 36. Y One of the panel frameunits 22 will be associated with the upper edge of the pair of kiclrplates 35 while one of the spacing bar sections or units 14 will beassociated with each vertical edge thereof. fr filler bar 37substantially U- shapedy in cross section will be associated with thelower edges of the kick plates 35. The webs of the units 14 are formedwith a plurality, here shown as two, apertures for the reception of tierods 20 which are passed longitudinally through the assembled unit inthe same manner as described in connection with the top rail section.yEach of the panel frame units 22 is provided with an overhang- Vingledge or shoulder 33 the underface of which is bevelled as indicated at39 and in assembling this unit with the kick plates 35 the lugs 36 arecaused to engage behind the flanges 23 with `the upper edges of the kickplates abutting the inclined lower faces 39 of mee-,eea

Thelflerunit 37 is provided at each end with an extension or tongue 40ywhich is adapted Vto.v project through a slot 4l formed inthe: lower endof each ofthe units 14.

in assembling the unit 34 the hller member V3.7 is: arranged with theextensions 40 thereof projectingl through theslots 4l of the units i4and with the upwardly extending iianges 'l 42l thereof engagingl underthe lugs The panel trame unit 22 is assembled with the up.-

per edges: ot' the kick plates 35 inthe manner aforesaid and the tievrrods 20 are put into positionwith the nuts 2l thereoic Aloosely threadedupon these tie rods. This unit is then assembled with the lower endsotthe side rails, by sliding the same longitudinally of the side rails.vas suggested in Figure 7 with the dovetail ribs 19 of the; spacing barsections i4 slidablyengaging the dove-tail grooves 13 ot the side railsections l0. This section 34 is moved to a position wherein/thechanitered or bevelled portions 3l ofthe panel -training units 22,engage whereupon the lower ledge ofthe unit 34 isin alignment with thelower ends of thesiderail sections. In this position of the parts .thenuts 21 are in alignment with the apertures 32fforined A. in the outerwalls of the side rails whereupon these nuts Amay be tightened to bindthe several elements ot the panel 34 together and to cause a bindingactionbetween the spacing bar units 14 and the side rail sections tounite these units 84 as a. whole with the .side `rail sections l0.

Whilethe form of door illustrated in Figi ure l involves a structurewherein the greater a tion to the panel 34.
